Fertile soils are an important requirement for agriculture. Basic soil constituents are minerals, humus, moisture and air. Soil ability to grow plants is certainly affected by the increase or decrease in the proportion of its these essential constituents/comments. But how we can measure the soil fertility precisely and what is the easiest way to measure it.
There is no better tool than crop response. If you are in a position to precisely measure the existing nutrient constraint in a given soil with respect to a crop , and later establish the favorable crop response with the addition of the constrained nutrients , you can easily quantify various limits of soil fertility vis-a-vis crop yield.This is the reason , we keep saying , SOIL HEALTH CARD has to be based on specific crop.......plus target yield , unfortunately in perennial fruit crops, a different dynamics work in this context.....
Since Soil fertility is the ability of soil to provide plant habitat and result in sustained and consistent yields of high quality.
The ability to supply essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and the absence of toxic substances which may inhibit plant growth. So plant growth and performance will help in measuring the soil fertility.
Anoop Kumar Srivastava thanks for useful response regarding soil fertility measurement.
